Industrial combustion processes can generate high emissions or require very low emissions that need more than a single-step solution. At LAB, we design and deliver combined flue gas treatment systems that integrate multiple technologies into a fully optimized and compact solution, ensuring comprehensive compliance with environmental standards across all regulated pollutants.
From dust and acid gases to dioxins, heavy metals, and NOx, our combined systems are engineered to adapt to your specific emission profile, process constraints, and regulatory targets.
Why Choose Combined Systems?
- To comply with very low BREF, or local regulatory limits
- To treat very high pollutant concentrations like hazardous waste and sludge incineration
- To integrate heat recovery by flue gas condensation and future Carbon Capture
Our Expertise in Multi-Stage Configurations
Depending on flue gas composition and process, LAB combines its proprietary technologies to build the most efficient solution. Typical combinations include:
BicarLAB ® + DeNOx SCR + SecoLAB ®
→ Sodium bicarbonate dry system with high potential for acid gas removal + NOx reduction on catalyst without reheating + dry system with lime and activated carbon
Delfzijl, Netherlands
VapoLAB ® + DeNOx SCR + wet scrubber
Dry system with high acid gas removal potential + NOx removal at catalyst + polishing scrubber for very low emissions (optional including condensation).
Komorany, Czech Republic
ESP+ DeNOx SCR+ SecoLAB ®+ Wet Scrubber
DeNOx SCR downstream ESP at high flue gas temperature + SecoLAB ® for first acid gas removal and activated carbon injection downstream external eco + wet system for complete acid gas reduction (optional including condensation).
- No reheating for DeNOx SCR
- Easy integration of condensation
- Very high removal efficiency
